How Much Does Each Part of Deck construction Cost?

The cost to build a deck in Allentown ranges from $3,920 to $17,650, with most homeowners paying around $8,330. Your actual cost depends on several factors specific to your home and the Allentown-Bethlehem market.

🔌

Deck cost scales directly with size — a 200 sq ft deck costs roughly half of a 400 sq ft deck for the same material and height.

Pressure-treated wood is cheapest ($15–$25/sq ft), composite costs $25–$45/sq ft, and exotic hardwoods run $30–$60/sq ft installed.

Height And Stairs

Elevated decks need taller posts, more bracing, and stairs — each set of stairs adds $500–$2,000 depending on height and material.

🔧
Railing Style

Basic wood railings cost $20–$40/ft while cable, glass, or composite railings run $60–$150/ft installed.

Permits And Engineering

Most jurisdictions require a building permit ($100–$500) and may require engineered plans for elevated decks, adding $300–$1,000 in design fees.

The Northeast tends to have higher labor costs, partly driven by stronger union presence and higher cost of living. Stricter building codes mean more inspection requirements — budget extra for permits.
